UCEC 8000mAh Wii U Gamepad Battery, Wii U Battery Replacement Rechargeable Battery Pack Wii Accessories for Nintendo Wii U WUP-010, WUP-012

Fit perfectly. my Wii U controller now holds a charge! Installation was easy, the screwdriver provided is small, but effective. Make sure to use the provided pad so that the battery doesn't rattle around.

Installation is a bit different compared to other batteries and an included sticky foam pad is used to keep the battery in-place and prevent impact. I believe the active use battery life could be as far as 8 hours but just leaving it on idle for the past 12 hours it's still going very strong. Extremely good performance value.

Awesome battery for the Wiiu after recently having to change its old battery from having it for 11 years this new battery is a massive upgrade over the original one the new battery life is amazing and the quality is so good easy to install now I don’t have to worry about getting a new battery replacement it’s like giving a whole new life to the Wiiu

The first battery I received was well-packaged but unfortunately didn’t hold a charge at all. I contacted Amazon, and they quickly sent me a replacement, instructing me to discard the defective one. It was great not having to deal with the hassle of returning it, and the new battery has been perfect! Installation was super easy—just loosen two screws, unplug the old battery, insert the new one, and tighten the screws. I saw some other reviews mention that the battery didn’t fit properly, but I had no issues at all. There was plenty of room, and everything fit as expected. The longest we’ve used it without charging was at least 10 hours, and it still had a good amount of battery left. I place the gamepad on the dock at night, and it lasts the entire next day without needing a recharge until bedtime. My kids are thrilled they can play whenever they want now. Definitely worth the purchase!

This battery worked for a little while... kind of. When I first installed it, it seemed to power the gamepad, but it did cause the gamepad's charging light to occasionally blink. I thought that as long as it worked, I could live with a sometimes blinking light. However, I guess this was a sign that something was wrong. After a few uses, I found that the battery was dead and it would not charge. Thinking that maybe the battery wasn't fully plugged in, I opened the battery door and unplugged and replugged it several times but with no success. It simply would not charge anymore (if it ever did in the first place). Of course, I discovered this problem right after the return window ended, so I guess I'm out of luck. Maybe I just got unlucky and received a defective unit, but it seems the seller may need to work on quality control. :-(

This is ridiculously easy to install. It comes with the screwdriver. You just fully remove the back (just screws holding in place. No wires. No issues) then stick this one in and close it up. I have the oldest model of Wii U. I ordered it as soon as orders became available. This battery fit in and worked with mine with no issue. It’s great. It charges quickly. I know I’m in the minority, but I love the Wii U and used to kill the battery all the time. I love the enhanced battery life of this unit.

Absolutely worth it. This battery is five times longer than the original. Someone said they got 10 hours on high brightness and you can probably get more with less brightness. Easy install took 2 min.

Fits good, four hours in and it is still fully charged.
